Shrub rose plant named ‘Poulcot004’

ABSTRACT

A new garden rose plant of the shrub rose class which has abundant, red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poulcot004’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant that originated from a controlled crossing between the femaleseed parent, an unpatented rose named ‘Kormixal’ and the male pollenparent; an unnamed seedling.

The two parents were crossed during the summer of 1995, and theresulting seeds were planted in a controlled environment in Fredensborg,Denmark. The new variety is named ‘Poulcot004’.

The new variety may be distinguished from its female seed parent by thefollowing combination of characteristics:

-   -   1. Flowers of ‘Kormixal’ are red in coloration while flowers of        ‘Poulcot004’ are a pink red blend.    -   2. ‘Poulcot004’ has smaller leaflets than ‘Kormixal’.

The new variety may be distinguished from its male pollen parent fromthe following combination of characteristics:

-   -   1. The male pollen parent has white flowers while ‘Poulcot004’        has red flowers.    -   2. ‘Poulcot004’ has fewer flower petals than the male parent        plant.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant red flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots;    -   3. Disease resistance;    -   4. Profusion of decorative rose hips.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulcot004’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 1995 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘Poulcot004’ was selected in the spring of 1996 by the inventor as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulcot004’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July 1996. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulcot004’ are true to typeand are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcot004’, as observed in itsgrowth in a field nursery in Jackson County, Oreg. Observed plants are 2years of age, and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 2001, except where common terms of color areused.

For a comparison, several characteristics of the rose variety‘Poulrijk’, a rose variety from the same inventors described andillustrated in U.S. Plant Pat. No. 12,519 issued Apr. 2, 2002, arecompared to ‘Poulcot004’ in Chart 1.
